4 Common Causes of Rippling Asphalt Shingles

If your asphalt shingles appear rippled or buckled, chances are there is a moisture-related issue or another underlying problem with your roof that needs to be addressed as soon as possible. Understanding the common causes of this particular dilemma can help you determine the best roof repair or maintenance strategy. 

Continue reading to find out four of the usual culprits behind this roofing issue.

1. Poor Ventilation
   Once you spot rippling or buckling shingles on your roof, make sure you inspect the ventilation in your attic right away. A well-ventilated attic allows moisture inside your home to escape through exhaust vents. If the ventilation is blocked or insufficient, moisture can begin to build up and condensate on the underside of your roof, resulting in rippled or buckled shingles. Improving your attic ventilation can easily resolve this problem.

2. Wind Damage
   In some cases, asphalt shingles begin to ripple or buckle because strong winds have lifted them. If there is no creasing in the shingles, you can smooth them down by reapplying adhesives. If the shingles have started to crease or crack, a replacement may be necessary.

3. Water Leaks
   Without regular inspections, leaks in pitched and flat roofing systems can become rampant. A leak will first penetrate the shingles, then accumulate in the underlayment for some time before making its way to the decking. Like with poor ventilation, the trapped moisture within the roofing system will affect the shingles over time, causing them to buckle.

4. Re-roofing
   Re-roofing refers to the installation of new shingles over old ones. While this technique is allowed in some states, oftentimes it does more harm than good. The problems with the old shingles will not be addressed, and moisture will likely be trapped under the new shingles with nowhere else to go. This moisture will then be absorbed by the new shingles, causing them to ripple.
